Description

Technical Field

[0001] The utility model relates to the technical field of experimental equipment, in particular to a Wright staining rack for glass slides. Background Art

[0002] Before observing a blood smear under an optical microscope, it needs to be fixed and stained. Fixing is to quickly crosslink and solidify components such as cell proteins and polysaccharides to keep the original morphological structure of the cells unchanged. Staining is to stain the main structures of cells, such as cell membranes, cytoplasm, and cell nuclei, with different colors for easy observation and identification under the microscope. Most blood smear staining methods are derived from Romanowsky staining methods, and commonly used ones include Wright staining method and Giemsa staining method. The Wright staining method makes the cells colored by both chemical affinity and physical adsorption. Due to the different chemical components contained in various cells, their affinities for dyes are also different. Therefore, after staining, various cells show their respective staining characteristics.

[0003] The staining steps of Wright staining are usually as follows: After blood collection, prepare a blood smear with appropriate thickness; draw lines at both ends of the blood film with a wax crayon, and then place the blood smear flat on the staining rack; add several drops of Wright stain to cover the entire blood film, and stain for about 1 minute; add about an equal amount of buffer solution to mix with the stain, and stain at room temperature for 5 - 10 minutes; rinse off the stain with running water, and wait for it to dry before microscopic examination.

[0004] The existing Chinese utility model patent with the publication number CN209296427U discloses a Wright staining rack for batch use, including a box body, a fixed rod, a lifting rod, a lifting mechanism, and glass slides. The two ends of the fixed rod are respectively connected to two opposite inner walls of the box body. The axis of the fixed rod is parallel to the bottom surface of the box body. A lifting mechanism is arranged in the box body. The lifting rod is connected to the lifting mechanism. The lifting rod is parallel to the fixed rod. The glass slides are lapped on the upper ends of the fixed rod and the lifting rod.

[0005] The existing technology has the following technical defects: The above-mentioned Wright staining rack uses a fixed rod and a lifting rod to support the glass slides. Electric telescopic rods are respectively arranged at both ends of the lifting rod to realize the lifting of the lifting rod. Furthermore, the glass slides can be in an inclined state during the running water flushing process for easy cleaning. However, when the glass slides are placed on the fixed rod and the lifting rod, the positions of the glass slides are not fixed, which may lead to differences in the flushing effects of the glass slides. When the lifting rod is lifted and lowered and during running water flushing, the glass slides may slip. At the same time, electric telescopic rods are arranged at both ends of each lifting rod, resulting in a high cost. Summary of the Utility Model

[0006] In view of this, the purpose of the present utility model is to provide a slide Wright staining rack to solve the problems in the prior art that the positions of the slides placed on the fixed rod and the lifting rod are not fixed, resulting in differences in the rinsing effect of the slides, the possibility of the slides slipping during the lifting of the lifting rod and the running water rinsing, and the relatively high cost.

[0007] The present utility model solves the above technical problems through the following technical means: A slide Wright staining rack includes a box body. A rotating rod is rotatably installed on the inner wall of the box body. One end of the rotating rod protrudes outside the box body. A driving component for driving the rotating rod to rotate is arranged on the outer wall of the box body. A plurality of slide support plates are arranged at intervals along the axial direction of the rotating rod, and the slide support plates rotate with the rotation of the rotating rod.

[0008] Further, a worm gear is fixedly sleeved on the end of the rotating rod located outside the box body. An installation shell is arranged on one side of the box body. A worm and a crank are arranged on the installation shell. The worm is rotatably installed between the inner walls of the installation shell and meshes with the worm gear for transmission. One end of the worm protrudes outside the installation shell and is fixedly connected to one end of the crank.

[0009] Further, a plurality of clamping plate cavities penetrating the rotating rod are arranged at intervals along the axial direction of the rotating rod. A clamping plate is fixed at the middle position of the bottom of each slide support plate.

[0010] Further, a baffle is arranged at one end of each slide support plate, and the thickness of the baffle is less than the thickness of the slide.

[0011] Further, a drain hole is opened on the box body.

[0012] The beneficial effects of the present utility model are as follows:

[0013] 1. By placing the slides on the slide support plates, the positions of the slides are fixed, ensuring the consistency of the rinsing effect. At the same time, the slides will not slip during the rotation of the rotating rod and the running water rinsing.

[0014] 2. By driving the rotation of the worm and the worm gear through the crank, the rotation of the rotating rod can be controlled, and then the slide support plates can be rotated. When adding Wright stain and buffer solution, the slides can be placed flat on the slide support plates. When it is necessary to rinse the stain with running water, the slides tilt with the rotation of the slide support plates. The structure is simple, easy to use, and the cost is relatively low.

[0022] As Figures 1-3 shown, an embodiment of the present utility model provides a Wright staining rack for glass slides, which includes a box body 1. The box body 1 is formed by enclosing a bottom wall and four side walls. The top of the box body 1 is open. A rotating rod 2 is rotatably installed on the inner wall of the box body 1. One end of the rotating rod 2 protrudes outside the box body 1. A driving assembly for driving the rotating rod 2 to rotate is arranged on the outer wall of the box body 1. A plurality of glass slide support plates 4 are arranged at intervals along the axial direction of the rotating rod 2. One glass slide can be placed on each glass slide support plate 4. The glass slide support plates 4 rotate with the rotation of the rotating rod 2.

[0023] In this embodiment, a plurality of rotating rods 2 are equidistantly arranged along the length direction of the inner wall of the box body 1. The structure of each rotating rod 2 is the same. Such a structural design can perform Wright staining on multiple glass slides simultaneously, improving the experimental efficiency.

[0024] Actually, the driving component can be a motor. A motor is arranged at one end of each rotating rod 2 protruding out of the box body 1, and the output end of the motor is fixedly connected to the corresponding rotating rod 2. In this embodiment, a worm gear 8 is fixedly sleeved at one end of each rotating rod 2 located outside the box body 1. An installation shell 73 is arranged on one side of the box body 1. The installation shell 73 is also formed by enclosing a bottom wall and four side walls. One end of the installation shell 73 is open, and the open end of the installation shell 73 faces the side wall of the box body 1 and is fixedly installed on the box body 1. With such a structural design, the inside of the installation shell 73 is in a sealed state and will not be wetted by flowing water during the glass slide rinsing process, providing good protection for the components inside the installation shell 73. A worm 9 and a crank 10 are arranged on the installation shell 73. The worm 9 is rotatably installed between the inner walls of the installation shell 73 and meshes with the worm gear 8 for transmission. One end of the worm 9 protrudes out of the installation shell 73 and is fixedly connected to one end of the crank 10. With such a structural design, by rotating the crank 10, the user can drive the worm 9, the worm gear 8, the rotating rod 2, the glass slide support plate 4, and the glass slide to rotate, so as to control the glass slide to be in a flat state or an inclined state. The structure is simple, easy to use, and has a low cost.

[0025] Actually, the glass slide support plate 4 can be fixed on the rotating rod 2. In this embodiment, a plurality of clamping plate cavities 5 penetrating the rotating rod 2 are arranged at intervals along the axial direction of the rotating rod 2. A clamping plate 6 is vertically fixed at the middle position of the bottom of each glass slide support plate 4. The glass slide support plate 4 is installed and positioned by inserting the clamping plate 6 into the clamping plate cavity 5. It should be noted that the friction coefficient between the clamping plate 6 and the inner wall of the clamping plate cavity 5 should not be less than 0.25, and the materials of the two can be selected such as wood, silicone rubber, etc. With such a structural design, the glass slide support plate 4 is convenient to install and disassemble, quickly positioned, and convenient for maintenance and replacement. At the same time, during the rinsing process, only by slightly tilting the glass slide support plate 4 at a certain angle can the flowing water flow down smoothly. Under the action of the clamping plate 6, the glass slide support plate 4 can rotate well following the rotation of the rotating rod 2.

[0026] A baffle 11 is arranged at one end of each glass slide support plate 4. The thickness of the baffle 11 is less than the thickness of the glass slide, further increasing the positioning effect of the glass slide support plate 4 on the glass slide.

[0027] A drain hole 12 is opened at the bottom of the upper side wall of the box body 1, facilitating the discharge of liquid from the box body 1 during the flowing water rinsing process.

[0028] Working principle:

[0029] After blood collection, prepare a blood smear with appropriate thickness by using the crank 10 to adjust the glass slide support plate 4 to a horizontal state. Draw lines at both ends of the blood film with a wax crayon, then place the blood smear flat on the glass slide support plate 4, add several drops of Wright's stain to cover the entire blood film, stain for about 1 minute, add about an equal amount of buffer solution to mix with the stain, and stain at room temperature for 5 - 10 minutes. Then, use the crank 10 to adjust the glass slide support plate 4 to an inclined state, rinse off the stain with running water, and examine under a microscope after drying. The utility model realizes simultaneous rinsing of the glass slides after staining, can perform Wright's staining on multiple glass slides at one time, improves work efficiency, each glass slide is placed on the glass slide support plate 4 in the same state, and the staining consistency and rinsing consistency of the glass slides are good, ensuring the accuracy of the experiment. The structure is simple, easy to use, and has a low cost.
